SYNTHESIS OF MOLECULAR SIEVING METALLOSILICATES USING SILICA-TRANSITION METAL OXIDE SOLS

摘要

A method is disclosed for the preparation of a molecular sieving metallosillicate wherein an aqueous dispersion of colloidal particles comprising contiguous mixtures of silica and at least one oxide of a transition metal is mixed with an effective amount of a mineralizing agent and/or synthesis directing agent to form a gel. The formed gel is maintained at a temperature of about 80.degree.C to about 300.degree.C for a period of time effective to provide the desired molecular sieving metallosillicate.
